Abstract
The utility model relates to a flange cross-over connection earthing device can be dismantled in thermal power plant's ammonia district. The former ammonia district flange cross-over connection earth connection of current thermal power plant is 4x4 patchcord crimping wiring nose, and the earth connection inner core is the patchcord, and the wiring nose mismatches with the flange bolt, has the earth connection broken string, and wiring line nose contact failure phenomenon, the unqualified phenomenon of ground connection, and be unfavorable for work such as other professional flange overhauls, has increaseed the maintenance degree of difficulty. A removable flange cross-over grounding device, comprising: the ammonia region flange (1) and the fixing device (2), the fixing device is composed of two horizontal plates (2-1) and a vertical plate (2-2), a metal layer is electroplated on the fixing device through an electro-galvanizing process, the horizontal plates and the vertical plate are of an integrated structure, the horizontal plates and the vertical plate are of a U-shaped structure, and open type rhombic clamping grooves (3) with the same specification as bolts are formed in the horizontal plates. The utility model discloses be applied to ammonia district flange overline ground structure of thermal power plant.
Description
Technical Field
The utility model relates to a flange cross-over connection earthing device can be dismantled in thermal power plant's ammonia district.
Background
The former ammonia district flange cross-over connection earth connection of current thermal power plant is 4x4 patchcord crimping wiring nose, and the earth connection inner core is the patchcord, and the wiring nose mismatches with the flange bolt, often has the earth connection broken string, wiring line nose contact failure phenomenon, and the unqualified phenomenon of ground connection, and be unfavorable for other professional flange overhauls, has increaseed the maintenance degree of difficulty of overhauing.
